IMPROVEMENT IN SPRING ATTACHMENTS TO CAR-WINDOWS.

Specification forming part of Letters Patent No. 135,086, dated January21, 1873.

To all whom it may concern:

Be it known that I, GEORGE CORNWALL, of Brooklyn, in the county of Kingsand State of New York, have invented a new and-Improved SpringAttachment to Oar-Windows, of which the following is a specification:

Figures 1 and 2 are side views of car-windows provided with myimprovedspring attach ment, showing them in different positions. Fig. 3 is aface view of the same.

Similar letters of reference indicate corresponding parts.

This invention relates to a spring attachment to the sashes ofcar-windows, and more particularly to such sashes that are let down intoboxes of the car-frame when opened; and has forits object to prevent therattling of said windows when openedorclosed and consequent annoyance topassengers. The invention consists in the application to each upper endof sash of one or more U-shaped inverted springs, whose ends arefastened to the faces of the sash, while their upper rounded partsproject above the sash, andcome in contact with the frame of the windowto prevent rattling either in closed or open positions of the sash, andto lowering the sashes, as described hereinafter. In the drawing, theletter A represents the sash of the car-window fitted into the frame Bin such manner that it can be let down, as in Fig. 1, whenever thewindow is to be opened,

Fig. 1, and thereby prevent the sash from rattling in the box; and whenthe sash is raised,

- as in Fig. 2, the outer face or faces of the springs 0 bear againstthe lintel a or upper part of the window-frame, as shown in Fig. 2,andprevent rattling in equal degree.

The springs are of such form and so applied as to keep the sash out ofcontact with the casing on either side; and likewise to adapt them toserve as handles for raising and lowering the sash, thus rendering theprovision of other or the ordinary hoisting-straps unnecessary.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

The arrangement of the bow-spring G with the sashA and easing B, asshown and described, whereby it prevents rattling, and also serves thepurpose of a handle, as specified.
